That's it. He locked Galifrey away. But now that I think of it I don't remember him locking Skaro too. However if he did lock Galifrey he must have done with when the Dalek ships were orbiting around the planet.

If that's the case, the Dalek ships (with the Daleks inside), and Galifrey would have been the only things affected. So theoretically Skaro is free to travel too﻿
